All it will take is another scandal and he'll have to go surely? I mean, what about if there were a juicy sex scandal? Imagine the fall-out if he was using his taxpayer funded transport to travel around London and see lots of women, or something else like that? Now that would be juicy, and hilarious at the same time wouldn't it? Mind you, the Lobby might be to scared to report something like that even if he did!
The really question I guess is how long he can hold on with the current scandals engulfing him. Perhaps it won't need another one to force him out of office. After all, he is fast losing the support of Labour MPs and he has now got the support of Galloway. Will Brown dither over Livingstone or will he act decisively against him? On past performance the former rather than latter seems most likely.
